Wilfred Spiegelenburg commented on YARN-8792: --------------------------------------------- None of these changes fit into the integrated way we currently implement the rules in the FS and CS. As part of YARN-8948, YARN-9298 and finally integrated in YARN-8967 this has been changed. Both schedulers now use the same placement manager and placement rule code. The placement of the application in a queue is moved out of the FS also. > Revisit FairScheduler QueuePlacementPolicy > ------------------------------------------- > > Key: YARN-8792 > URL: https://issues.apache.org/jira/browse/YARN-8792 > Project: Hadoop YARN > Issue Type: Improvement > Components: fairscheduler > Affects Versions: 3.1.1 > Reporter: Shuai Zhang > Assignee: Shuai Zhang > Priority: Major > > Fair scheduler use `QueuePlacementPolicy` to map a request to queue.
